manufacturer, a subject of the German Emperor, residing at 18 Heinrichstrasse, Han

over, Germany, have invented certain new and useful Improvements in Nicotin-Absorbers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i Y

My invention relates to an improvementjin nicotin-absorbers for abstracting the nicotin and other 'deleterious substances from tobaecofsmoke like.

For absorbing the volatile deleterious substances containedin smoke, in particular those bases of which nicotin, nicotinann, and pyridin are the most important, porous or absorbent materials--such as cottonvwool, felt, meerschaum-waste, and the like-have hitherto been employed. The materials were generally inserted either in the pipe stem or bowl, so that theV tobacco-smoke was made to pass through them. The absorbing power of these materials is, however, very small, in particular as no chemical action takes place therewith. Also they are not adapted to effect a perfect filtration of all the smoke, a portion of the latter passing through without being acted upon, and consequently passing in an unpurified condition into the mouth.

The present invention has for its object' to obviate these defects.

It consists in the employment of peat ber, in particular that of the very absorbent mosspeat, as the material for absorbing the nicotin and other deleterious constituents from tobacco-smoke- The application of this material is effected in the same way as the'materials heretofore used. A plug of the peat p is formed, and this is introduced into the lower part of the pipe-bowl or in' the chamber for collecting the liquid. In the case of small pipes and cigar-mouthpieces the plug is placed in the hollowspace of the mouthpiece, or with small pipes having a separate bowl of meerschaum and the likel a special tube of aluminium or other suitable metal is introduced between the bowl and mouthpiece, into which tube the plug is inserted. This tube with in pipes, mouthpieces, and thel part of the smoker.

the mouthpiece can,.af ter removing the bowl, be also used as a cigar-holder.`

piece immediately in front of the tobacco.

Figure l shows a .vertical section through a pipe-'bowl containing a nicotin-absorber according to my invention in the lower part. Vci is the upper part of the pipe-bowl.

b is the lower part of the pipe-bowl that is connected by means of the chamber forcollecting the liquid with the tube of the pipe. cis the plug of peat fiber.

Fig.`2 shows'a vertical section through a pipe-bowl containing a nicotin-absorber acpatented inne, ieo.

For cigavrettes the plug can be inserted in the mouth o is the plug of The porosity of peat, 'in particular mosspeat, enables it to be used in a much denser condition than is possible with cotton, wool, felt, meerschaum-waste, and the like without requiring an increased suction on the Thus a milch more perfect filtration of the whole of the tobacco- :smoke is eected before it reaches the mouth.

The jiltering-surface with which the smoke comes in contact is considerably greater than ployed Without interfering with the' smoking.`

Furthermore, the peat ber exercises a. chem chemically with the bases of the smoke,'so

that they are not merely retained mechanically. Such acids of the peat have not deleterious effect. s The tobacco-smoke is therefore vpurified both by chemical and by mechanical means by the peat before itfarrives in the mouth.
